Just under a month ago Hennessey Performance unveiled their HPE650 package for the Boss 302 Mustang. The HPE650 package added an Eaton TVS 2300 supercharger along with various other upgrades to ramp up the power of the Boss 302 to over 650 horsepower. Not one to rest on their laurels the Hennessey Performance team is at it again with two new Boss 302 upgrade packages.

The Hennessey HPE490 package takes a stock Boss 302 and adds an HPE designed cold air induction, long tube headers, high flow cats, and a custom engine tune. The result is a bump of about 48 horsepower, increasing the Boss 302's output from 444 to 492 horsepower. As with all of Hennessey's Boss 302 upgrade packages the HPE490 includes unique exterior badging and serialized dash and engine plaques.

For the enthusiast who needs it all and more Hennessey is also offering the HPE700 Boss 302 supercharger package. Hennessey took the same Eaton TVS2300 supercharger featured in the HPE650 package and added a smaller pulley for more boost. To aid in the additional manifold pressure Hennessey also added a Kenne Bell Boost-a-Pump system which increases the fuel flow of the fuel pump at full throttle. The Hennessey HPE700 Boss 302 creates about 700 horsepower at 7000rpms and comes with a 3 year / 36,000 mile warranty.
